An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-22439 in the wild and no public exploit code.\n\nAffected product: Gallagher Controller 6000/ Controller 7000. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-22439/ (Markdown: https://insights.sbomify.com/CVE-2023-22439/index.md)","id":"CVE-2023-22439","markdown":"https://insights.sbomify.com/CVE-2023-22439/index.md","name":"CVE-2023-22439","record":{"aliases":["GHSA-4jpc-fv5p-mh98"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Gallagher access controller","requires_auth":"none","summary":"Attackers can cause a denial of service in the diagnostic web interface of Gallagher access controllers by sending large HTTP requests.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gallagher","cpe":[{"product":"command_centre","vendor":"gallagher"},{"product":"controller_6000_firmware","vendor":"gallagher"}],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper input validation of a large HTTP request in the Controller 6000 and Controller 7000 optional diagnostic web interface (Port 80) can be used to perform a Denial of Service of the diagnostic web interface.\n\nThis issue affects: Gallagher Controller 6000 and 7000 8.90 prior to vCR8.90.231204a (distributed in 8.90.1620 (MR2)), 8.80 prior to vCR8.80.231204a (distributed in 8.80.1369 (MR3)), 8.70 prior to vCR8.70.231204a (distributed in 8.70.2375 (MR5)), 8.60 prior to vCR8.60.231116a (distributed in 8.60.2550 (MR7)), all versions of 8.50 and prior.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in Controller 6000/ Controller 7000","id":"CVE-2023-22439","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Intel(R) SCS Add-on software installer for Microsoft SCCM","id":"CVE-2023-22440"},"packages":[],"prev":{"headline":"Cross-site scripting in EC-CUBE 4 series, EC-CUBE 3 series, and EC-CUBE 2 series","id":"CVE-2023-22438"},"products":["Controller 6000/ Controller 7000"],"published":"2023-12-18","related":[{"cvss_score":9.9,"headline":"Missing authorization in Command Centre","id":"CVE-2021-23140","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":9.9,"headline":"SQL injection in Command Centre","id":"CVE-2021-23230","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":9.9,"headline":"Missing authorization in Command Centre","id":"CVE-2020-16096","kev_date_added":null,"published":"2020-09-15"},{"cvss_score":9.8,"headline":"Information disclosure in Command Centre","id":"CVE-2020-16098","kev_date_added":null,"published":"2020-09-15"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2019-15294","kev_date_added":null,"published":"2019-08-28"},{"cvss_score":9.1,"headline":"Information disclosure in Command Centre Server","id":"CVE-2024-21815","kev_date_added":null,"published":"2024-03-05"},{"cvss_score":8.8,"headline":"Memory corruption in Command Centre","id":"CVE-2020-16103","kev_date_added":null,"published":"2020-12-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-02","vendors":["Gallagher"]},"summary":"Attackers can cause a denial of service in the diagnostic web interface of Gallagher access controllers by sending large HTTP requests.","url":"https://insights.sbomify.com/CVE-2023-22439/"}
